Paper Abstract

Förster type energy transfer offers opportunities as a sensitive and frequently selective method of monitoring the concentration of analytes in medical sensing applications. However, the fluorescence quenching kinetics observed in microheterogeneous media such as tissue are likely to be less than ideal. In the present article, the quenching kinetics of the carbocyanine dye DTDCI by transition metal ions in solutions and in the microheterogeneous polymer Nafion (a registered trademark of Dupont Corporation) are reported and compared with a view to understanding the complex fluorescence kinetics likely to be encountered in biological media.
